The ChatGPT desktop app saves pages into your Showspace from a local project, and its MCP settings take the app's address for the app's commands.
ChatGPT is OpenAI's assistant for everyday questions and longer jobs. A toggle above the message box switches between Chat and Work, an agent mode that stays with a task and produces finished documents, sheets and web pages. It suits anyone who wants a report, a plan or a dashboard without writing code.
It runs in a browser, on your phone and as a desktop app for the Mac. The desktop app opens and changes files on your Mac, which is how pages get into a Showspace.

Good to know
We use ChatGPT with lite.computer ourselves.
Files ChatGPT makes on the web are kept in its Library. Download them from there into your Showspace and they appear in lite.computer.
For coding work in the same desktop app, see Codex, which shares the app's settings.
The steps above are for the ChatGPT desktop app released on July 9, 2026. The earlier Mac app is now called ChatGPT Classic.
ChatGPT creates images, and it is the tool we use to make every image on lite.computer. Ask for photos or illustrations in a report, and ChatGPT builds them into the page.
Questions
Does ChatGPT work with lite.computer?
Yes. In the ChatGPT desktop app, attach your Showspace to a local project and the pages it saves show up in lite.computer. Add the app's address under MCP servers in its settings to give it the app's commands as well.
What is ChatGPT Work?
Work is an agent mode in ChatGPT, next to Chat. It gathers information across your apps and files and produces finished pages, documents and sheets. In the desktop app it works in the folders you attach, including your Showspace.
What is ChatGPT Classic?
It is the earlier ChatGPT app for Mac. When OpenAI released the new ChatGPT desktop app on July 9, 2026, with Chat, Work and Codex in one place, the old app was renamed ChatGPT Classic. See also Codex.
